This is one of the reviews from Amazon:

"Very unfortunately, "New Headway Elementary", which used to be an excellent British English textbook, has now been converted into a horrible mish-mash of British and American, with a strong American bias. Recommended for Americans maybe, but definitely not recommended for British English."

Maybe it's good to have some understanding of both versions of English. But I think that you'll have to focus on one variant, in my case British English. When I'm going to learn the two together, I think I'm messing things up and then maybe people don't understand me. But then, trusting on two reviews from Amazon.co.uk is not enough, so I would like to hear some more comments.
